Dual Nozzle Extruder?
Would there be any way to make a dual nozzle extruder for the Prusa Mk3S?
I often find myself preferring to use either a 0.4mm or a 0.2mm nozzle between different prints, sure you can change the nozzle, but it is not exactly a straightforward enough process to just want to do it between prints.
Would it be a viable future upgrade to have an extruder that had both a 0.4mm AND a 0.2mm nozzle mounted on it, so that you could toggle back and forth between the 2 sizes without mechanical intervention (i.e. the same way you can select which steel sheet is being used via the control panel)?
or even some apparatus that you could rotate, like how you select a different lens size on a microscope...
This would be a far more useful feature than multiple filaments... 1 filament feeder... 2 nozzles.
Thanks,
Check out the tool changer print ...
There's a print in the print library to convert your X chassis into a tool changer ... for your dual nozzle idea, you would need dual hot ends, since the nozzle is mated to the heat break physically to control the leakage. That would then take dual filament feeds and some way to swap which one is getting hot ... and that would make the extruder head enormous ...
